Interior view of a spiral staircase at the Palazzo Contarini del Bovolo (also called Palazzo Contarini Minelli dal Bovolo). The Palazzo Contarini del Bovolo is a small palace in Venice, best known for the external spiral staircase with a plethora of arches, known as the Scala Contarini del Bovolo (of the snail). The palace dates from the 15th century and is apparently in poor state of restoration, while the staircase leads to an arcade provides a charming panoramic vista over some of the roof-tops of the city. The palace is located in a less-traveled side-street near the Campo Manin, near the Rialto...Subject photograph(s) are copyright Edward McCain.
